I think that instead of doing 2 RAID 1 arrays, you better have to do 2 RAID
0 array. If one disk fail in a RAID 1 array, It could bring the entire
array down (I ever saw such a thing), and your RAID 0 array will be down
too. But in the other case, if a drive fail, it will only bring down the
RAID 0 array, but NOT the RAID 1 one.
I have tested the two setup, and I think that the second (RAID 0 then RAID
1), is the most reliable.
